Amazon adding HTML5 support to new Kindle Format 8

October 24, 2011

Kindle Format 8 is the company’s next-generation file format for Kindle books, and will supplant Mobi 7 in this capacity. According to Amazon, KF8’s richer formatting capabilities will enable increased design latitude for children’s books, comics, technical and engineering books, cookbooks, and more.

CSS3 support should allow for the easy creation and/or translation of previously difficult-to-format tables, boxed elements, and even Scalable Vector Graphics. Embedded fonts, callouts, sidebars, and text on background images will also be possible.

The upcoming Kindle Fire (previewed here) will be the first Kindle device to support KF8, and while Amazon did not specify exactly which other e-ink devices will support the new standard, the company says that in coming months, “we will roll out KF8 to our latest generation Kindle e-ink devices as well as our free Kindle reading apps.

Also left unmentioned is when app versions of the Kindle service will benefit from KF8 support.

Amazon also announced that it will be releasing enhancements to its Kindle Publisher Tools suite that will make it easier and faster for publishers to create better-looking Kindle books, and that upcoming new versions of the KindleGen (KindleGen 2) and Kindle Previewer (Kindle Previewer 2) will allow for easier book building and previewing options.
